Hi everyone. I ran a search but did not find anything. I listen to mp3's on my default Music app on my iPhone 4S every day. I use my stock pair of Apple ear buds as well. When I get system sound notifications sometimes, the volume of my music gets really low and does not come back to normal volume after the system sound is completed. The only way that I've figured out how to correct this is to go into my System settings > Sound > and play my ringtone and then switch back to my music and it returns to the default volume I originally had it set at. Has this been addressed before? Am I doing something wrong here?
